Schizosaccharomyces, Octosporomyces, Hasegawaea, fission yeastsAbstract
Although the genus Hasegawaea was introduced along with the recognition of the genus Octosporomyces in the classification of fission yeasts, the two additional genera were neither accepted nor recognized. However, the genus Schizosaccharomyces sensu Kurtzman et Robnett was taxonomically heterogeneous-natured and corresponded to a higher-ranked taxon, i.e., a monotypic family. Thus, the following three genera were confirmed in the family Schizosaccharomycetaceae. The genus Schizosaccharomyces sensu stricto was comprised of Schizosacchromyces pombe,the genus Octosporomyces was of the three species, Schizosaccharomyces octosporus, Schizosaccharomyces osmophilus, and Schizosaccharomyces cryophilus as Octosporomyces octosporus, Octosporomyces osmophilus, and Octosporomyces cryophilus, and the genus Hasegawaea was of Schizosaccharomyces japonicus as Hasegawaea japonica. In conclusion, the precise classification of microorganisms will not be able to be expected in the generic designation without the presence of taxonomic homogeneous-natured taxa. The phylogenetic distances have to be absolutely considered. Namely, the longer the distances are, the more taxonomic heterogeneous natures will be increased in the resulting genus.
